[PATCH 18/36] ARM: OMAP2+: gpmc-onenand: Move Synchronous setting code to drivers/
From: Roger Quadros
Date: Wed Jun 11 2014 - 04:58:34 EST
Move the code that puts the onenand in synchronous mode
into the appropriate place i.e. drivers/mtd/onenand/omap2.c.
Make use of omap_gpmc_get_clk_period() and omap_gpmc_retime()
to calculate the necessary timings and configure the GPMC
parent's timings.
